Molecular cloning, bacterial overexpression, characterization and functional introgression into tobacco conferring salt-tolerance phenotype. J. Biol. Chem. 279 28539-28552. 

Recently the PINO l gene of the salt-tolerant wild rice Porteresia coarctata (Roxb.) was found to encode a salt-tolerant MIPS enzyme, as compared with the MIPS encoded by the salt-sensitive cultivated rice (Oryza sativa L.) (Majee et al., 2004). Comparison of MIPS sequences in these species revealed distinct differences in a 37 amino acid stretch, which upon deletion from the salt-tolerant MIPS rendered it salt-sensitive. Introgression of the PINO I gene via transformation rendered tobacco salt-tolerant. The genome of cultivated rice contains one gene encoding MIPS, termed RINOl. In addition to constitutive and... 

The type strain is PA51 (= LMG 21291 = MTCC 3852 ), isolated from mangrove-associated wild rice Porteresia coarctata) in Pichavaram, Tamil Nadu, India. The DNA G+C content of the type strain is not reported.
